The NX Nastran Advanced Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material nonlinearities and/or geometric nonlinearities (that is, large deformations).An add-on module of NX Nastran – Basic, the Advanced Nonlinear solver is an integration of the well-known and highly regarded ADINA solver into NX Nastran as Solution 601 for implicit solutions or Solution 701 for explicit solutions. The integration of the ADINA solver into Solution 601/701 is transparent to the user because the input and output formats are based on NX Nastran formats. Thus, to the user, the experience and usage of Solution 601/701 is completely Nastran-centric.
